HUBBLE SPACE TELESCOPE
DAILY REPORT #1700
PERIOD COVERED: 0000Z (UTC) 08/19/96 - 0000Z (UTC) 08/20/96
Daily Status Report as of 233/0000Z
1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:
1.1 Completed Two Sets of FOS/RD 6914 (FOS Cycle 6: Location of =
Spectra and Wavelength Calibration - Red Side)
The Faint Object Spectrograph (Red Side) was used to make both a =
TALED and a wavelength calibration image. All observations were made =
using internal light sources. This proposal will be executed a total of =
12 times during cycle 6 (i.e., once per month). The observations were =
executed as scheduled, and no anomalies were noted.
1.2 Completed FOS/BL 6498 (Accretion Streams in Magnetic Variables: =
FOS Eclipse of 4 Rosa)
The Faint Object Spectrograph (Blue Side) was used to make rapid =
mode spectrographic observations of the accretion streams in the magnetic =
variable star (i.e., cataclysmic variable) RXJ1940-10 (aka, 4 Rosa). =
This is a binary system, and it contains a white dwarf star, an accretion =
disk, a mass stream, and hot spot where the mass stream hits the disk and =
a companion star. An FOS target acquisition for this proposal, at =
232/0329Z, was not successful, and HSTAR 5694 was written. Otherwise, =
the observation completed and no further anomalies were reported.
1.3 Completed FOS/RD 6595 (Does Pluto Have a Haze Layer?)
The Faint Object Spectrograph (Red Side) was used to make =
spectrographic observations of the planet Pluto in order to determine if =
the planet has a haze layer. These observations were made during a =
series of stellar occultations. The objective is to study the physical =
structure of the atmosphere at kilometer-level spatial resolution. The =
observations were executed as scheduled, and no anomalies were noted.
1.4 Completed FOS/RD 6097 (UV Spectroscopy of Radio Loud AGNs With =
Double Peaked Emission Lines)
The Faint Object Spectrograph (Red Side) was used to make =
ultraviolet spectrographic observations of the active galactic nuclei in =
radio galaxy 3C332. This galaxy is reported to have double peaked =
emission lines. These observations are to test competing models for the =
origin of the broad lines and to define the properties of the host galaxy =
in the ultraviolet. The observations were executed as scheduled, and no =
anomalies were noted.
1.5 Completed WF/PC-2 6909 (WF/PC-2 Cycle 6 Calibration: Earth Flats)
The WF/PC-2 was used to make observations of the bright earth to =
obtain streak flats which are used to construct high quality flat fields =
for the WF/PC-2 filter set. The observations were executed as scheduled, =
and no anomalies were noted.
1.6 Completed GHRS/2 6076 (XI BOO A: Structure and Non-Thermal =
Heating)
The High Resolution Spectrograph (Side Two) was used to make high =
resolution spectrographic observations of the binary system star HD131156 =
(aka, XI Boo A and B) in order to study its structure and non-thermal =
heating. From these data an improved value for the electron density will =
be obtained. The observations were completed as planned, and no problems =
were reported.
